How to create/change a default template

So. there is this Twenty Ten 1.1 by the WordPress team Theme.
A company wants its own theme similair to that one, with more pages, but same for each employee who wants to join the Companies blog.
So the stupid question is - how do i make a template that can be used to automatically create a personal blog for an employee the same way that theme is applied.

I read this posthttp://en.forums.wordpress.com/topic/how-to-import-wordpress-themes
- But i cant believe it is not possible? I mean if i have root access to the installation of WP (which i by the way do not have now) - is this possible? Should i just change the original Twenty Ten 1.1 by the WordPress team Theme to what they want it to be?

- Is there a way to do so in the application (i.e. not changing the low code, but using the software or the web-client)

- Or what is the easiest/simplest way to get to such a condition where the default would be the one the company needs.

Thanx!
(I understand, if the twenty ten is on the companies server, and it is a folder with php files, all that is needed is to change it (someway) and that is it...right )

I mean if i have root access to the installation of WP (which i by the way do not have now)

That leads me to believe you do not know the differences between wordpress.COM and wordpress.ORG blogs, and since you have access to the "root" it tells me you are in the wrong forum and heed to head over to http://wordpress.ORG/support/ as that is where self-hosted wordpress blogs are supported.

Sorry but we only answer questions pertaining to free blogs from and being free hosted by wordpress.com. The two (wordpress.com and wordpress.org) are entirely separate. Here's that link to the correct support forum again http://wordpress/org/support/
